1. what method of mass production increased the supply and reduced the cost of the automobile?

the moving assembly line

Explanation:

The assembly line was one of Henry Ford's greatest contributions and achievements. On November 13, 1913, Henry Ford first used a moving assembly line to mass produce a complete car. This "invention" reduced the time necessary to manufacture a car from 12 hours to 2.5 hours, and it lowered the price of cars significantly (model T).

Ford's moving assembly line relied heavily on worker specialization and changed the way factories worked around the world.
